So, you want to update the bios of your lenovo x250 by downloading this iso from that page?

Read this readme. But also read the following lines. Lenovo missed "just some little facts".

First of all, I was not able to dump that iso to an usb stick by using dd. Secondly and most importatn, you have to go in your bios setup and change your boot up way from "legacy" to "uefi". After you have done that, your burned optical disk will boot up and you can finally upgrade your bios.
